HINGE Specification of Letters Patent.

Patented Sept. s, 1908.

Application filed November 25, 1907. Serial No. 403,680.

To all whom it may concern:

Be it known that I, RALPH P. HAWLEY, a citizen of the United States, anda resident of Monongahela city, in .the county of WVashington and Stateof Pennsylvania, have invented a new and Improved Hinge, of which thefollowing is a full, clear, and exact description. I

This invention is an improvement in hinges, relating more es ecially tohinges for Waffle-irons and other c evices in which it is unnecessary toseparate or revolve the hinge members on each other as much as 180, usually no appreciable distance over 90.

The object of the invention primarily is to provide a hinge inwhich themembers thereof are rigid with their respective pivots, and

- may be separated or lifted apart when the hinge is open. I

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of a hinge embodying my invention asapplied to a wafile-iron; Fig. 2 is a cross-section on the line 2-2 ofFig. 4, looking in the direction of the arrow; Fig. 3 is an inner faceview of one of the hinge members; and Fig. 4 is a side elevation of thehinge, showing the base of the waffle-iron in section, and one of thehinge members in a dotted position as when fully open.

I have shown for convenience my improved hinge in connection with awaffle-iron, the latter comprising the cylindrical base 5, in the upperedge of which are provided notches, in which are revolubly mounted thetrunnions, one-half of each being formed on each section 6 of the iron,the said sections having the usual handles provided with theoppositelydisposed grips 7. The trunnion of the iron embodying the hingeof the two iron sections, and which is the principal feature of myinvention, is composed of two separable hinge members 8, 8, of likeconstruction, each hinge member having in the present instancesemi-cylindrical shanks placed together to provide the trunnion for theiron, and is cut out on a central vertical plane at one side to providea shoulder 9. In the angles be tween the shoulders 9 and the flat facesof the shanks of the hinge members, the members are provided withrounded alining pivots 10, integral or otherwise rigid with theirrespective hinge members, the pivots being arranged on a median line ofthe hinge, each fitting into a corresponding groove formed in theopposed hinge member. The hinge members are constructed at the oppositeside or outside of the pivots 10, with extensions 11, which, in theposition of the hinge as shown, are ofi-set in a vertical plane to bringtheir under faces in a longitudinal central plane of the hinge and incontact when the hinge is closed, thus preventing the hinge members frombeing lifted apart or separated when in closed position, but making themreadily separable when one of the members is revolved to the dottedposition illustrated in Fig. 4. i

As is best observed in Fig. 3, the extensions 11 of the hinge membersare also laterally off-set to provide the pointed or substantiallywedge-shaped projections 12,which are adapted to be alternately engaged,when the sections of the waffle-iron are separated, in a notch 13 formedexteriorly of and in a thickened portion of the cylindrical base 5. Thisengagement prevents the waflle-iron from revolving on its trunnions whenthe sections of the iron are open.

The shoulders 9 of the hinge members are made to conform to the outerfaces of the extensions 11, whereby a substantial seating surface isprovided when the hinge members are fully separated, and in whichposition said members may be readily lifted apart.

\Vhile I have shown my improved hinge in connection with a waffle-ironin order that one of its many applications might be fully understood, Inevertheless recognize that the hinge will'be found valuable in manyother relations, and consider that I am entitled to such modificationsas fall within the scope of the claims annexed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1; The combination of a cylindrical base, and hinge members havingsemi-cylindrical shanks placed together and revolubly mounted in thebase, each hinge member having a rounded pivot rigid therewithandfitting in a corresponding groove in the opposed hinge member, andprovided with a laterally off set extension, one of said extensionsbeing adapted to engage with a notch in the base and prevent rotation ofthe shanks thereon, and the other provide a seat for the opposite hingemember when the hinge members are separated on their pivots.

2. A hinge ,comprising two separable hinge members having pivots, eachpivot being rigid with its respective member and fitting into a groovein the opposed member, said members having contacting faces at each sideof the pivots and arranged at the oposite sides of the longitudinalcenter of the inge, whereby the members cannot be bodily separated whenthe hinge is closed.

3. A hinge comprising two separable members each having a pivot rigidtherewith fitting in a groove in the opposed member, said members havingoppositely-arranged faces movable into contact at both sides of thepivot when the hinge is closed.

4. A hinge, comprising two members hav ing alining pivots, each pivotbeing rigid with its respective member, each of the members bein cut outat one side at substantially right-ang es to its pivot to provide ashoulder, and an extension rigid with each member, adapted to contactwhen the hinge is closed and providing a seat for the shoulder of theopposite hinge member when the hinge is open.

5. A hinge comprising two separable members of like construction, eachmember having a pivot rigid therewith fitting into a groove in theopposed member and provided with an extension adapted to contact withthe extension of the other member and prevent the separation of saidmembers when the hinge is closed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
